The PV Power Map is a report of national solar resource availability as illustrated by the monthly energy output of a nominal 1-kilowatt (kW) photovoltaic (PV) system by location. This issue highlights the difference in real-time production when compared to annual averages. The first map illustrates total estimated power output for the month of April 2012. The second shows the average monthly PV power output in 2011.

Spreadsheet The spreadsheet shown here, refined and updated over five years, is our ongoing attempt to summarize the economic and carbon-footprint efficiency of cars you can buy now, or in the near future. Note that it includes a few sample used cars. The carbon generated in manufacturing any car usually exceeds the carbon emissions for [...]

The PV Power Map is a report of national solar resource availability as illustrated by the monthly energy output of a nominal 1-kilowatt (kW) photovoltaic (PV) system by location. This issue contains two maps: one generated using SolarAnywhere’s satellite time-series irradiance data, and the other using National Renewable Energy Laboratory Typical Meteorological Year (TMY3) data. Comparing these two maps highlights why TMY3 data are not recommended to predict short-term performance.
